Patent NO-169150-C (NO)
Inventor: PREIS JOSEF
IPC: H02H9/00
Filed: 1987-12-23
Abstract: Circuit arrangement for limiting the switch-on current and for overvoltage protection of switched power supply apparatuses having an input-side storage capacitor (12), which forms a low-impedance voltage source for a power supply arrangement connected thereto. Such a power supply apparatus is intended to be provided with a circuit which not only limits the switch-on current but also ensures protection against overvoltages on the storage capacitor (12). This is achieved with the aid of a field-effect transistor (11) arranged between the supply voltage source (1) and the storage capacitor (12), which is not only controlled by an amplifier in the sense of current limiting but is also controlled by a delay member in the sense of delayed switching on. The power supply apparatus is particularly suitable for plug-in assemblies with voltage converters for supplying electrical telecommunications devices.

Abstract: A method and apparatus for regulating a measurement system.  The apparatus includes a coordinator that transmits instruction signals based upon a program stored in a memory to an instrument through a communication bus. The instrument is also coupled to a device under test. A real-time synchronized clock and a data buffer are placed on each instrument that performs a measurement, provides a stimulus, controls a device, manages data, or performs a test. Signals passing between the device under test and the instrument are processed by function circuitry. After the measurement is made and a parameter or an output signal from the device under test is collected by the instrument, the real-time clock supplies a reference time signal which is associated with each parameter or group of data derived from the device under test. The data buffer stores each group of data with its associated reference time signal until the coordinator calls for the instrument to dispatch the results of the measurement or stimulus back along the communication bus in the form of an instrument output signal. If the instrument provides a stimulus to the device under test, the stimulus appears as an input signal in accordance with the instruction signal which has been stored in date buffer. The stimulus is triggered by a timing signal from the real-time clock.

Title: Object sensing system for bar code laser scanners
Inventor: MARWIN GREGG
IPC: H01S5/042
Filed: 1992-02-28
Granted: 2002-08-20
Abstract: In a bar code laser scanning system operable in a continuous scan mode and a sleep mode, an object sensing circuit for automatically switching said laser scanning system from the sleep mode to the scan mode is provided to help extend the operational lifetimes of the system compo-nents such as the laser diode and the scanning motors.      When in the sleep mode, pulsed light is received and pro-cessed to generate a steady state voltage signal. Derived from the steady state voltage signal is a positive thresh-old voltage signal and a negative thaveshold voltage signal each having a magnitude respectively greater than and less than that of the steady state voltage level. The steady state, positive threshold and negative threshold voltage signals are input to a comparator means which detects when an object is placed in the scanning field of the laser scanning system. Object detection occurs when the steady state voltage increases above the positive threshold voltage signal or decreases below the negative threshold voltage signal depending upon the object's reflectivity.      When an abject is detected, a trigger signal is provided to direct the laser system to switch back into the scan mode without interrupting the normal scanning process.

Abstract: A data processing system has a store, logically partitioned into different partial spaces, for storing vector data consisting of different elements.  The system also has address translation buffers, logically partitioned into pages of sizes prescribed for respective partial spaces, for translating the logical page number for each partial space to a physical page address.  An address translation controller is provided for, when any of the vector data stored in the store is to be accessed and if the elements are within the range of a prescribed number of pages, searching different entries in the address translation buffers, performing simultaneous address translation of the pages, and thereby accessing the vector data.  The number of simultaneously accessible elements is determined on the basis of the between-elements distance of the vector data and the size of the page of the partial space to which the desired vector data belong.  The invention improves the efficiency of the store and increases the throughput of vector data processing.

Abstract: A novel method and apparatus are provided for making an improved welded joint between overlapping lengths of thermoplastic strap.  The welded joint includes a central region and an adjacent peripheral region.  The pressure on the strap joint during formation is released first in the peripheral region and subsequently in the central region.  An embodiment of the apparatus for making such a joint includes an anvil, a central strap-engaging member, a peripheral strap engaging member, and a mechanism for moving the anvil sequentially to three positions.  At a first position the overlapping strap lengths are pressed between the anvil and both the central and peripheral strap-engaging members.  In the second position of the anvil the peripheral strap-engaging member does not press against the strap lengths while the central strap-engaging member continues to press the strap lengths against the anvil.  In the third position of the anvil the anvil and strap-engaging members are sufficiently spaced apart to release all of the pressure on the strap lengths.
